Specification of Letters Patent.

Patented May 21, twin.

Application filed March 9, 1918. Serial No. 221,494.

To all whom it may concern:

Be it known that 1, ANDREW W. JUDY, a citizen of the United States, residing at Centerville, in the county of Appanoose and State of Iowa, have invented a new and useful Gar-l vheel, of which the following is a specification.

The subject of the present invention is a car wheel of that style commonly used on mining cars.

The main object within the contemplation of the invention is the production of a roller bearing wheel which may be readily cast without the necessity of the formation of a core. a

The invention also contemplates the provision of means for locking the wheel on the spindle of the aXle.

A still further object of the invention is the provision of means for closing the end of the hub.

The invention likewise contemplates the production of a simple, durable and eflicient wheel.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawing, wherein Figure 1- is a diametrical section of a wheel constructed in accordance with the invention;

Fig. 2 is a view in elevation of the locking collar, the locking wings shown in opened position in dotted lines.

Referring to the drawings by numerals of reference A wheel constructed in accordance with this invention is preferably cast integral and is formed with a hub 1 cored to receive a cage 2 supporting rollers 3. The inner end of the hub has a reduced core to receive the spindle 4 with a close turning fit.

Webs 5 extend radially from the hub 1 and connect the flanged rim 6 to the hub, the hub, rim and webs being integral.

The outer end of the spindle 4 is formed with an annular groove 7 which is adapted to receive the inner edges of the arcuate wings 8 which wings are pivotally secured to a collar or washer 9.

A cupped plug 10 has a close sliding fit in the outer end of the hub 1 and the annular flange of its cupped inner end encircles the collar 9 and its arcuate wings 8 to retain the wings with their inner edges seated in the annular groove 7 and so look the wheel on the spindle.

A split cotter pin 11 is inserted through diametrical alining bores formed in the outer end of the hub 1 and the plug 10 for the purpose of locking the plug in place in the hub.

It will be seen from the shape of the wheel and its hub that the same may be cast directly from the impression of a pattern without the formation of a separate core,

thus reducing the time and labor necessary for casting the wheel, and, consequently, reducing the cost thereof.

Having thus described the invention, what is claimed as new and sought by Letters Patent, is

1. A car wheel, including a spindle having an annular groove at its outer end, a wheel rotatable on the spindle, a collar adapted to be seated in the groove, and means insertible in the wheel to lock the collar in the groove and lock the wheel on the spindle.

2. A car wheel, including a spindle having an annular groove at its outer end, a wheel having a hub rotatable on the spindle, a collar adapted to be seated in the groove, a plug insertible in the hub and engaging the collar to retain the same in the groove and lock the wheel on the hub, and means for locking the plug in place.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my sign ture in the presence of two witnesses.

ANDREW w. JUDY.
